The weight of the load suspended on the rubber cord is 500 g. Determine the stiffness of the cord if it stretches by 5 cm. (Enter a number without SI units, the coefficient of free fall can be taken as 10 N / kg)
Formula for solving the problem: Mg = kx / 2
K is the stiffness coefficient, x is the change in elongation, m is the mass, g is the acceleration of gravity.
K = 2mg / x
K = 2 * 0.1 * 10 / 0.0025 = 800
